private SeekBar seekBar;
private TextView textView;
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        seekBar = (SeekBar) findViewById(R.id.progress);
        textView = (TextView) findViewById(R.id.text1);
        seekBar.setProgress(15);//设置节点初始位置
        textView.setText("15");//设置节点初始值
        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                // 当拖动条的滑块位置发生改变时触发该方法,在这里直接使用参数progress，即当前滑块代表的进度值
                //textView.setText("Value:" + Integer.toString(progress));
                //Toast.makeText(MainActivity.this, "正在滑动！"+ progress, Toast.LENGTH_SHORT).show();
                textView.setText(Integer.toString(progress));
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {
                //Log.e("------------", "开始滑动！");
                Toast.makeText(MainActivity.this, "开始滑动！", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                //Log.e("------------", "停止滑动！");
                Toast.makeText(MainActivity.this, "停止滑动！", Toast.LENGTH_SHORT).show();
            }
